Huanhuan Wang says:

this series adds support for IPsec offload to the NFP driver.

It covers three enhancements:

1. Patches 1/3:
   - Extend the capability word and control word to to support
     new features.

2. Patch 2/3:
   - Add framework to support IPsec offloading for NFP driver,
     but IPsec offload control plane interface xfrm callbacks which
     interact with upper layer are not implemented in this patch.

3. Patch 3/3:
   - IPsec control plane interface xfrm callbacks are implemented
     in this patch.

Changes since v3
* Remove structure fields that describe firmware but
  are not used for Kernel offload
* Add WARN_ON(!xa_empty()) before call to xa_destroy()
* Added helpers for hash methods

Changes since v2
* OFFLOAD_HANDLE_ERROR macro and the associated code removed
* Unnecessary logging removed
* Hook function xdo_dev_state_free in struct xfrmdev_ops removed
* Use Xarray to maintain SA entries

Changes since v1
* Explicitly return failure when XFRM_STATE_ESN is set
* Fix the issue that AEAD algorithm is not correctly offloaded

    upper layer
